Have you considered how this might benefit those who are deaf, or speech impaired? Their lip/mouth movements might be totally different to folks with hearing - but if this can be fine-tuned on an individual's specific speech pattern, then I see a huge opportunity in the accessibility market for this too.

I would also attempt to patent this yesterday before Meta et al start bringing their own into the market. Heck - I wouldn't be surprised if Meta stepped in to aquihire all of you.
